Capacity Services
The Capacity service on Telefonica Wholesale's network backbone provides SDH/SONET circuits between its PoPs distributed through its fibre-optic network. These PoPs are located at points with a high degree of capillarity and access in the main capital cities where Telefonica Wholesale is present. The network maintains a unified structure regionally and globally through highly reliable and operationally flexible SDH/SONET, which makes it possible to guarantee provision of the service as quickly as possible (less than a week).
This Backbone SDH/SONET service offers a series of advantages for network and telecommunications carriers:
| ADVANTAGES | |
| Structured capacity with protection | The use of structured capacity in the SDH or SONET protocol guarantees a high level of quality and service availability. |
| Telefonica Wholesale PoP to PoP connectivity | Access to points of presence in each destination city is guaranteed by including Telefonica Wholesale's backhaul among its landing stations and PoPs. |
| Colocation | The equipment and space needed for connections can be adapted to the customer's needs. |
| Telefonica Wholesale Network Operation Centre Support and Services | Offers customers continuous support for the Capacity service in the provision and operation stages through centres that operate continuously 24x7. |
